*ARA Rules state: "1. Rifles--Any firearm chambered for the .22 Long Rifle cartridge may be used. There are no weight limits, no classes, and no dimensional restrictions to barrels, stocks, or limits on scope magnification. 2. Rests--Any rest may be used to shoot from the bench. One piece rests, separate front and rear rests, or sandbags may be used, so long as any such device prevents the barreled action from being affixed to the bench in an immovable manner."
